Can I add 5day old chicks to a new clutch

If you've been following my other post regarding horrible mama hen then you know I have 2 surviving chicks out of 7. I found one a little injured and decided to take it in, like right now. I have no idea what I am doing but just want to keep her well and alive. Anyway..as she's sitting in my blanket I will try and set up a box... A heating source is a bit of a challenge. I have to go to the marketplace and see about finding something I can use, ideally a hanging lamp. Anyway tomorrow I am expecting a new clutch with another hen and need to know if I can add these 5 day old chicks in with the new clutch. If I sneak them in will she accept them and will they pose a danger to the new hatchlings.

I left the other chick as it's doing fine and keeping quick to escape mama's feet as needed also because I am hoping that at night I can place this one back and take care of her throughout the day when mama is hyper-foraging
